Multicriteria Coordinated Control of Water Reservoir Systems in Case of Flood Emergency

In this paper we will present an approach to solving the problem of choice of an optimal reservoir control strategy in the situation of flood emergency. The potential and often adopted actions include spontaneous releases of water from the reservoir based on the emergency precipitation forecasts. As side effects, the water level sinks below the minimum necessary to sustain the ecosystems in reservoir lakes, while the fluvial ecosystems below the reservoir are often destroyed. We show that these effects may be minimised by a suitable coordination: the problem to be solved is a multicriteria coordination one, with the environmental, financial and human-life-protection-related criteria.
